To all whom it inay concern:

- HAU'PT, a citizen of the United States, and

Be it known that I, FREDERICK M. RUsoH- inexpensively produced and applied to either flat, curved, or angular surfaces,

The invention contemplates 'ashingle produced wholly from plastic materials without the use of any fabric or sheet material as a reinforcement, as from the composition of matter disclosed in Patent No. 1,051,769, issued to my assignee, American Flexible Slagge and Covering Co., on January 28th,

In the accompanying drawings, Figures 1 and 2 are perspective views showing sheets of two different forms which may be provided by the invention; and Fig. 3 is a diagrammatic view illustrating a step in a process-which maybe used for producing sheets of the form illustrated in Fig. 2.

The shingle forming the subject of this invention is produced by rolling a plastic material consisting of a mineral powder formed into a homogeneous dough-like mass,

by mixing therewith suitable quantities of a viscous material, such as the pitch or tar produced from the. distillation of coal or gum asphalt or asphaltic tar, or mixtures of-these substances. Ifgilesired a suitable coloring matter or surfacing material may be applied to the mass during the rolling operation, for varying the color or character of the surface of the sheet. 1

The shingles are desirably produced at a.

low cost by the use of inexpensive materials,

preferably those which maybe obtained in any locality. have found that shingles of very good quallty may be produced by usin thoroughly sifted ash from anthracite coa as the principal powdered mineral constituent, and by the use of coal tar pitch and coaltar axis the prmcipal constituents of the vised-s material. One formula principally Specification of Letters Patent.

containing these materials and serving to produce desirable sheets is that described in my said Patent No. 1,051,769 as follows In using the above formula I have found it desirable to thoroughly mix the dry constituents and viscous constituents separately, the viscous constituents being then, added to the dry materials" and the whole mass thoroughly mixed and kneaded at a suitable temperature, as in a steam jacketed mixing vessel. It will be understood that to enable the viscous materials to be thoroughly mixed with each other and with the dry materials,

it is necessary that they, first be melted, in accordance with the usual ing such materials.

The mass produced from the use of the formula above mentioned has a dough-like consistency when warm, and may be readily rolled out into sheets, of any desired size and thickness, from which the shingles, as 10 (Fig. 1) may be cut. Shingles so formed are tough. and but slightly flexible at the ordinary temperature. If warmed to a temperature of 100 degrees Fahrenheit, they ma be formed to any desired shape, as for fitting them into the gutters or over the ridges of roofs and the like. If desired shingles of the form shown at 11 (Fig. 2) and having the well known wedge shape form of wooden shingles may be produced. Shingles of the form shown at 10 (Fig. 1) or at 11 (Fig. 2) may belaid upon the roof in the same manner as wooden shingles. However, in covering a roof with such shingles the use of tin or other sheet metal in the gutters, and the like, is unnecessary; as the shingles herewith provided may be readily fitted into such parts of the roofand efi'ectively serve as a protection against the weather. 1

Sheets of the form shown at 11 ('Fig. .2)

practice of work- 85' are conveniently produced by rolling the before mentioned plastic material between ro ls, as 12, 13, (Flg. 3). For this purpose one of the rolls, as 13, is eccentrically mounted and is preferably of such size as to have a circumference equal to twice the length of I varied to produce the de varyin the finished shingle. If a quantity of the material, as 14, which has previously been reduced by rolling to the form of. a sheet having approximately the thickness of the thicker end of the 'shi e, be fed to these rolls while still warm, it will issuefrom the rolls in the form of a sheet 15 of gradually thickness,-'the amount of variation in thic ness being determined by the eccentricity of the roll 13. Obviously this may be e offta er desired in the finished shing es. The s ingles 11 are completed by cutting the sheet 15 transversely at the points of its greatest and least thicknesses, as at'16 and 17 (Fig. 3).

" If a colored or hardened surface is desired upon the shingles, a finely powdered or granulated material will be sifted upon the surface of the.unfinished sheet, as 14, im-

' mediately prior to its passage through the finishing rolls, as v12, 13. A desirable surface color' is produced by sifting finely powdered red oxid of iron upon the surface of the unfinished sheet,'-as 14. The character of the surface may be varied by the use of such substances as fine avel, crushed 4 mica, slate, or burnt'clay pro not, in a manner similar to 'that described for the red oxid of iron. In either case the surface of the shingle becomes thoroughly impregnated with the coloringor crushed material, and a permanent product is produced. It will be understood that shingles of either of the forms shown at 10, (Fig. 1) or 11 (Fig. 2)

may be produced with such modified; -surfaces.

fn applying the shingles to a roof they will be secured in place with nails and overlapped after the manner of laying ordinary Wooden shingles. The character of the sheets is such as to effectively resist the action of the Weather and wear, as also the action of acids or alkaline and abrasive cleansing materials. Furthermore, 'while the shingles contain a small proportion of com- ,bustible materials, these are of a character
